Updated 9/2003 Watershed Restoration Action Strategy (WRAS) State Water Plan Subbasin 20F Creek Watershed () Washington and Allegheny Counties

Introduction Subbasin 20F includes the 296-square mile Chartiers Creek watershed located in southwestern Allegheny and northern Washington Counties and the 19.4 square mile watershed of Sawmill Run, the upstream most named tributary flowing directly into the Ohio River. A total of 408 streams flow for 567 miles through the subbasin. Most of the tributary watersheds are small; only Little Chartiers Creek and Robinson Run have drainage areas greater than 30 square miles.

Chartiers Creek starts in a rural section of northern Washington County and flows north through Allegheny County and the western suburbs and through the Pittsburgh City limits to its confluence with the Ohio River near McKees Rocks. The subbasin is part of HUC Area 5030001, Upper Ohio River, a Category I, FY99/2000 Priority watershed in the Unified Watershed Assessment.

Geology/Soils: The entire subbasin is in the Western Allegheny Plateau Ecoregion. The upper third of the subbasin is in the Permian Hills (70a) subsection and the lower portion is in the Monongahela Transition Zone (70b) subsection. Strata are composed of sequences of sandstone, shale, limestone, and coal. The commercially valuable Pittsburgh coal underlies the entire subbasin. The upper basin was extensively deep mined starting in the late 1800’s, by the room and pillar method, with coal left in place to support the overlying rock and surface. The region supplied coal and coke for the numerous steel plants in the Pittsburgh region. More recent mines are far beneath the surface and employ the newer technique called longwall mining, in which huge blocks are removed, with the overlying rock collapsing soon after the coal is removed. The second most valuable coal is the Waynesburg coal, which is surface mined in the upper basin in Washington County. Significant extraction of the Upper Freeport coal also occurred. Oil and gas reserves were also located in the subbasin. Washington County was once a large producer of oil in . Oil production has declined to secondary production in established fields.

Soils in this basin are derived from noncarbonate sedimentary rocks. The infiltration rates are moderate, which allows for good hydrologic characteristics. The hilly terrain has shallow well-drained soils.

Land Use: Chartiers Creek watershed has a combination of urban, rural, forested, agricultural and surface mined land uses. The major urban areas are the city of Pittsburgh and its suburbs at lower Chartiers and Little Chartiers Creek, Cannonsburg at mid Chartiers Creek and Washington near the upper end of Chartiers Creek. This area was an important steel, railroad and manufacturing hub up to the early 1900’s. I-79 and I-70 pass through the subbasin. A suburban/urban corridor is adjacent to I-79 from Washington PA to Pittsburgh. Around 350,000 people lived within the subbasin as of the 1990 census; the population is projected to increase significantly to 520,000 by the year 2040.

Natural/Recreational Resources: Upper St Clair Township is completing a master plan for their 474-acre Boyce/Mayview Park, which is listed in the Allegheny County Natural Diversity Inventory as a significant biological diversity area.

The 76-acre PA Fish and Boat Commission (PFBC) owned Canonsburg Lake is located in the

1 Washington County portion of the watershed. A field survey by the PFBC in May 2000 indicated that the lake contains an excellent population of largemouth bass. A good population of large channel catfish is also present.

Chapter 93 designated Exceptional Value (EV) and High Quality Streams (HQ): EV: None. (HQ): • Reservoirs #2, 3 and 4 on upper Chartiers Creek • Little Chartiers Creek, from headwaters down to Alco Dam • Little Sewickley Creek

Water Quality Impairment The subbasin suffers from a variety of nonpoint and point source pollution sources. New and expanded municipal sewage treatment plants have resulted in water quality improvements over the past 20 years; however combined storm sewer overflows still carry considerable urban runoff into the streams. Habitat and stream channel modification g from urban development and impervious cover are also significant causes of impairment in the lower portion of the watershed. Portions of the watershed are also affected by agricultural activities and abandoned mine drainage (AMD).

AMD impairment is most apparent in the lower half of the watershed. Coal pillars left as support during underground mining allow pyretic material to come in contact with water in the flooded mines; water leaving the mines carries large loads of iron. Most of the mine discharges were acidic soon after they were flooded; however, many have become highly alkaline from contact with calcareous material in the overburden. The deep mines now discharge heavily iron-laden water to the receiving streams. These alkaline discharges are starting to be treated passively with constructed wetlands to remove the iron. Some of the active underground mines that are mining the extremely deep Pittsburgh coal in the Washington County portion of the subbasin have intercepted brines and discharge water that is highly alkaline with very high concentrations of total dissolved solids (TDS), sodium, chloride, calcium and sulfate. Some of these mines use longwall mining methods which can result in extensive areas of subsidence soon after mining. This subsidence can affect stream flow, highways and other surface structures.

Monitoring/Evaluation The DEP Southwest Regional Office inventoried subbasin 20F through the unassessed waters program in 1997. They reaffirmed the earlier 303d listings and added many additional stream segments to the list. The subbasin is has one of the highest percentages of impaired miles in Pennsylvania. A total of 461 stream miles or 84% of the subbasin are listed as impaired on DEP’s 2000 303d list. Only 87 assessed miles were determined to be attaining their water quality uses. Impairment sources were abandoned mine drainage, surface and subsurface mining, habitat modification, on-site wastewater, urban runoff/storm sewers, construction, and agriculture. In addition to nonpoint sources, 303d listings included fish consumption advisories for 30.37 miles of Chartiers Creek and 0.7 miles of Little Chartiers Creek for PCB and chlordane. The only assessed segments that were considered unimpaired are 49.73 miles of Little Chartiers Creek watershed and 37.46 miles of Robinson Run watershed. Discharges from oil and gas well production and storage and disposal of brines has also resulted in degraded surface and groundwater in some areas.

DEP biologists use a combination of habitat and biological assessments as the primary mechanism to evaluate Pennsylvania streams under the Unassessed Waters Program. This method requires selecting stream sites that would reflect impacts from surrounding land uses that are representative of the stream segment being assessed. The biologist selects as many sites as necessary to establish an accurate assessment for a stream segment. The length of the stream segment assessed can vary between sites.

2 Several factors are used to determine site location and how long a segment can be, including distinct changes in stream characteristics, surface geology, riparian land use, and the pollutant causing impairment. Habitat surveys and a biological assessment are conducted at each site. Biological surveys include kick screen sampling of called benthic macroinvertebrates, which are identified to family in the field, and an evaluation of their tolerances to pollution. Benthic macroinvertebrates are the organisms, mainly aquatic insects, that live on the stream bottom. Since they are short-lived (most have a one-year life cycle) and relatively immobile, they reflect the chemical and physical characteristics of a stream and chronic pollution sources or stresses. Habitat assessments evaluate how deeply the stream substrate is embedded, degree of streambank erosion, condition of riparian vegetation, and amount of sedimentation.

Future threats to water quality With the large projected increase in population for the basin, urbanization will to be a continued threat to water quality. Degradation from abandoned mines should decrease as passive treatment is used to treat discharges. Water quality should also improve with the expanded schedule of orphan oil and gas well plugging contracted by the Department’s Bureau of Oil and Gas Management.

Public participation/Outreach Watershed Notebooks DEP’s website has a watershed notebook for each of its 104 State Water Plan watersheds. Each notebook provides a brief description of the watershed with supporting data and information on agency and citizen group activities. Each notebook is organized to allow networking by watershed groups and others by providing access to send and post information about projects and activities underway in the watershed. This WRAS will be posted in the watershed notebook to allow for public comment and update. The notebooks also link to the Department’s Watershed Idea Exchange, an open forum to discuss watershed issues. The website is www.dep.state.pa.us. Choose Subjects/Water Management/Watershed Conservation/Watershed and Nonpoint Source Management/Watershed Notebooks.

A variety of federal and local agencies and staff from other Department programs reviewed or provided information for this WRAS. These included NRCS, the Bureau of Abandoned Mine Reclamation, Washington County Conservation District, and the DEP South West Regional Office. The public participation process has begun through distribution of this WRAS at various workshops and conferences and by the county conservation districts and DEP Regional Coordinators. Public input has been and will continue to be incorporated into expanding and fine tuning the WRAS for direction on use of 319 grant funds beyond FY2000.

Funding Needs The total needed dollars for addressing all nonpoint source problems in the watershed is undetermined at this time and will be so until TMDLs are developed for the watershed. The TMDL’s for AMD and nutrients and sediment in Chartiers Creek watershed and Cannonsburg Lake are scheduled for completion in 2001. The TMDL for PCB and Chlordane in Chartiers and Little Chartiers Creeks is scheduled to be completed by the end of 2000.

Pennsylvania has developed a Unified Watershed Assessment to identify priority watersheds needing restoration. Pennsylvania has worked cooperatively with agencies, organizations and the public to define watershed restoration priorities. The Commonwealth initiated a public participation process for the unified assessment and procedures for setting watershed priorities. Pennsylvania’s assessment process

5 was published in the Pennsylvania Bulletin, DEP Update publication and World Wide Web site. It was sent to the Department’s list of watershed groups, monitoring groups, and Nonpoint Source Program mailing list. Department staff engaged in a significant outreach effort which included 23 additional events to solicit public comment. The Department received 23 written comments from a variety of agencies, conservation districts and watershed groups. Pennsylvania is committed to expanding and improving this process in the future. After development of the initial WRAS a public participation process will take place to incorporate public input into expanding and “fine tuning” the WRAS for direction on use of 319 grant funds beyond FY2000.

Restoration Needs Restoration efforts have been lead by a variety of agencies and citizens groups, including the Western PA Coalition for Abandoned Mine Reclamation, Upper St. Clair Township, Chartiers Creek Watershed Coalition, and Chartiers Valley Nature Conservancy. Citizen volunteers under the direction of the Chartiers Valley High School and the Environmental Alliance for Senior Involvement (EASI) are monitoring the success of remediation efforts.

Chartiers Creek: The majority of the subbasin was determined to be impaired from a variety of pollutants caused by mining, urbanization and agricultural activities. Several assessments are underway which should lead to a better understanding of restoration and funding needs in the watershed. Two DCNR funded rivers conservation plans are underway, one for the Allegheny County portion and one for the Washington County portion. The Washington County Alliance started an assessment of Chartiers Creek as part of an evaluation of streams in the entire county. The TMDL for nutrients, sediment and AMD pollutants in the watershed is scheduled for completion in 2001.

McLaughlin Run: McLaughlin Run watershed was assessed using the principals of fluvial geomorphology. The study was funded through the 319 program. Results and recommendations of the study are as follows.

McLaughlin Run is a highly urbanized area in which increases in runoff have greatly affected the drainage system. The watershed is comprised of 21% impervious cover. Research has indicated that a sharp drop in stream water quality is seen at 10 to 15% impervious cover. Poor conditions begin occur at 25% imperious cover. The increased runoff and lack of stormwater control have increased channel erosion potential and sediment transport capacity of the streams. The increased sediment capacity has resulted in severe degradation of stream channels and banks. Channels have also widened so that they are encroaching on adjacent structures. Sediment accumulation has also restricted the active stream flow area. Many stream banks are highly eroded and unstable. Down cutting of the stream banks has resulted in habitat degradation such as loss of pool and riffle sequences and overhead cover.

The watershed assessment developed seven best management practices as strategies for stream bank stabilization and restoration. List of BMPs: 1. New channel construction or relocation 2. Bank stabilization by grading, rock structures or rock toe protection 3. Debris jam removal 4. Revegetation/riparian plantings with live cuttings or stakes and seedlings 5. Sediment transport efficiency 6. Traditional engineering channel stabilization methods such as riprap, gabbion baskets, precast concrete blocks, retaining walls, used tires, or natural vegetation 7. Stormwater control methods such as constructed wetlands, dry ponds, wet ponds, permeable paving material and filter strips, grass swales

6 The report mapped priority areas and described the specific BMPs recommended for each area. These recommendations when implemented will serve as a model for stream restoration in the urbanized areas around Pittsburgh and other parts of southwestern Pennsylvania. One implementation project was begun during summer 2000 with funding from the original 319 grant and another will begin the following year with a FY 2001 319 grant. The townships in McLaughlin Run watershed plan to apply for additional grants to fund restoration of the remaining stream segments.
